Deserts






Description
Any region that has very little life or plants may be called a desert.Arid deserts receive little precipitation and are charted by specialized plants that tolerate drought conditions and salty soils. There are no certain measure of how dry such an area must be to be called a desert.
Weather
There are no certain measure of how dry such an area must be to be called a desert.Deserts only recieve about 10 inches of rain which is basicly 25 centermeters of rain each year or some times less.Some times the rain evapourates before it even reaches the desert floor.Places with an average annual precipitation between 10 and 16 inches (25 and 40 centimeters) are called semideserts.Most deserts have at most a few days of rain each year, but some may get no rain at all for seven
years or get a whole years amount in one storm.It is hot in the day but cold in the night.

threats

One threat is over population.Another threat is water and human impact.Tourism we are people who love this wonderful planet we live on, our stampede to experience all the wonders of nature, but we could turn out to go up in history as the people who "love it to death".Farming - as the population on our planet continues to increase at an alarming rate , the demand for more products, needed to feed these millions of people, will also increase. With technology, it is becoming very easier to turn dry, arid desert habitat into farmland. Unfortunately, these lands are overcultivated and soon fall victim to desertification.Ranching - overgrazing is one of the major threats to the desert habitat. Mismanagement and overuse of land is putting severe pressure on desert habitat areas. Drilling operations - oil drilling operations in desert habitat areas alter the ecology of the desert. The high level of oil product usage in the world is destroying desert habitat. Pollution, produced by car exhaust, increases global warming, which, in turn, changes weather patterns. These changes result in climatic alterations that can shift the fragile balance needed to maintain the dry, arid conditions of the dese
Action
we can take action by using less water and and energy.
